A neurology expert has issued a pretty stark warning to denim-wearers after treating a woman who was trapped in her jeans and passed out on the side of the street.

Thomas Kimber describes the 35-year-old Adelaide woman's true nightmare in the latest issue of the journal Neurology, Neurosurgery and Psychiatry.

Apparently she passed out on the side of the road after trying to help a friend move while wearing skinny jeans, according to the Sydney Morning Herald.

"As she was squatting for a long period of time her trousers restricted the blood supply to both calves, and in response the muscles start to undergo stress and swell," wrote Dr Kimber.

She was then taken to Royal Adelaide Hospital, and because her legs had swollen so much, she had to have the jeans cut off by doctors.

"We were certainly surprised and shocked. It was a surprise to us that someone could get such severe nerve and muscle damage from the activity she described. The clothing she was wearing was the critical factor," said Dr Kimber.

And here is the important VERY REAL medical warning!

"The take home message is to avoid wearing skinny jeans if you intend to do a job with squatting or kneeling.

"If your legs begin to feel uncomfortable or tingle, you should stand up and get the blood circulating again."

You heard the good doctor... MOVE AROUND, DANCE, AND SLAY IN THOSE TIGHT JEANS. (It's good for your health.)
